Vidinhar was taken into custody late in the day on May 22, after their mother found the younger boys dead by at the family’s West Point home.

Vidinhar allegedly confessed to police that he killed the boys. He remains at Farmington Bay Youth Detention Center.

The teen has legal representation and was in court last week, where his attorney Todd Utzinger agreed to allow the county more time to review the evidence before moving forward.

“There is an advantage in us waiting,” Utzinger said Tuesday afternoon. “It provides us the opportunity to give more input into the county attorney’s office before charges are filed.”

Rawlings couldn’t say when charges are expected on the teen.

In a press statement released last week, Rawlings said the presumption the suspect is innocent remains “unless and until sufficient evidence to overcome the presumption becomes available. To date, evidence necessary to make the determination is not available to our office.”

The brothers’ mother arrived home from running errands on May 22 to find Benjie dead of stab wounds. When police arrived to help find the older brother and Alex, they found the 10-year-old’s body, which had also been stabbed to death, according to preliminary reports from police.

This tragedy is made worse, in part, because of the relative rarity of sibling murder, also known as fratricide.

A 2006 study from the Journal of the American Academy of Society and Law found that in these cases, adult siblings are most often the perpetrators. In fact, only 13 percent of offenders and less than 10 percent of victims were younger than 18, and most cases involved the abuse of drugs or alcohol. In a study of 10 cases, two offenders had schizophrenia or other psychosis, and one had depressive disorder, the journal reports.

A separate study found that all cases of murder by children, including instances of fratricide, were attributed to severe psychological disturbance.

A 2011 study published in “Patterns & Trends” by the U.S. Dept. of Justice found that about half of brothers who killed their own brother were between 16 and 30 years-old.

Articles about the West Point tragedy have been published worldwide in newspapers and on the web and television. They have been compared to the case of a Texas teen who allegedly murdered his mother and 15-year-old sister after watching a horror film in January of 2013 and raised concerns about adoption and sibling rivalry.
